Aqua Hot loud banging noises
Hey gang, I've had a weird thing happening with my Aqua Hot unit. The unit performs as it should, but shortly after the diesel burner ingites......and for the duration of its run.....there's a loud bang....two, maybe three times under there. It's like someone is laying on their back in the basement banging on the chassis and floor with a small sledge.
I've stuck my head in the Aqua Hot bay while running, and it's not coming from the unit itself.
Aqua Hot tech told me about an air relief hole in the exhaust pipe that must be obstructed. My dealer and Winnebago factory couldn't find any.
I'm heading to Gaffney in June, perhaps they can assist somehow.
Any ideas on what's happening?
